FWIW, I don't know if it helps at all, but there's a concrete example of allowing a 3rd-party product to add a section to zope.conf via %import in the ClockServer product at http://www.plope.com/software/ClockServer/ .

I'm looking back and forth between the Zope and ZConfig sources and documentation to see if I can figure out how to have a Product (or a python package) to extend Zope's ZConfig schema (a.k.a. Zope/Startup/zopeschema.xml) without having to reach into the guts of ZConfig. It looks like the right way to do this would be to extend Zope's schema and then specify a different 'schemafile' to ZopeOptions, but that's not currently possible as Zope doesn't support the '-S schemafile' switch that ZDCtlOptions does. If what I'm looking for seems just stupid please tell me *wink*. All I want to do is to add a simple config 'key' to zope.conf without having to patch the Zope source. Having no other choices, I would go with having my own schema and configfile, but that would be sub-optimal.

[Zope-dev] 2.9 goals
I'd like to propose/sponsor/promise-to-finish the following for inclusion in 2.9. If anyone has fears/doubts/problems with specific things, please let me know. I can also start a 2.9 project on the wiki with this info; if other folks have features they want, maybe they can post them here and we can put together a release plan. Definitely: - Chris Theune's blob support for ZODB (currently on the ctheune-blobsupport branch in ZODB's SVN repo) - Speed up large PUTs: http://mail.zope.org/pipermail/zope-dev/2005-April/024617.html - Implement RESPONSE.isClientConnected() to be able to tell if the client that made the request is still connected (allow long-running app code the possibility to abort processing if it notices the client is not connected). Maybe: - Include ClockServer: http://plope.com/software/ClockServer - ZODB connection policies, which will allow you to associate a thread pool with a particular set of ZServer servers. This will allow sites which are having resource exhaustion problems (e.g. running out of threads, running out of database connections) to continue to be accessible via servers running on special ports for debugging and maintenance purposes. It should also allow site admins to associate a particular thread pool with connections from spiders and other cache-busters by associating particular user agents or other request parameters with a thread pool. Work towards this was done on the chrism-zserver-connection-policies-branch branch in CVS a while back.

Adding this ability would be a new feature, so not available until 2.9. I got the impression people want to do this now. It makes a lot more sense to pick something that can be used both now and into the future than hack something together. If someone wants to create a way to manage product-specific configurations in a single file, it's not hard to create a Python package to support that, and products that want to have their configuration placed in that file could set themselves up to use %import in that file. I've no need of that myself, but others are certainly welcome to create such a package; it may be a reasonable addition for 2.9, and could be distributed separately for use with 2.7/2.8. -Fred -- Fred L.
